Remember, if the car was in the showroom, it likely had gobs of tire shine on the sidewalls. That will add greatly to any understeer feel you were noticing. AWD cars also need to be driven differently than rwd to get optimal performance. You will have to learn how to drive it.


I have a supercharged M3 for sale which I have set up for track use and drive occasionally in canyon-type drives. I'm used to a RWD car that turns in and rotates under trail braking and/or throttle.

My experience with the STI felt really strange - any throttle input added a motion to the front of the car toward the outside of the turn. It wasn't really understeer or push - just a weird movement of the nose outward and then inward when I lifted.

Here's my question. Is this what I should expect with the EVO too? Is this just a characteristic of AWD? Since I only could rev to 3K, I really couldn't try anything with the throttle. [/B]
Again, AWD cars handle differently than rwd cars. The 'punch the throttle to get the car to rotate' thing that RWD drivers do, is not so effective in AWD. While you can get rotation in the Evo this way, it's rotation is a bit sluggish. The rotation you do get is due to the front tires grabbing the road. The Evo rotates much better with just plain throttle modulation....ie lift.

For all intents an purposes, the Evo should handle much better than an M3. It just goes about it differently.

Is it possible to tune an EVO for 300+whp and still have a decent power and torque band?

Thanks for listening to my ramblings - it's late. [/B]
Yes, this is very easy to do. All you need is have your ECU reflashed for $600 and you are already hitting 300hp. Add an exhaust and you pick up a few more.

300 WHP with exhaust and Xede by Vishnu. Faster than stink and more fun than a 911. Excellent handeling in all conditions. I love this car (I had the STi for 800 miles and sold it).

Strange....In my Evo 3000 RPM in fifth gear equates to 70 mph. Maybe that Evo handled a little better than you thought??????

Adios,

sounds like bad apexing. what driving school did you graduate from?

It's your driving style coupled with the cleaning products used to make the tires shiny on the dealer floor.

If you do end up getting an Evo, learn to drive it before you start randomly swapping parts to (hopefully) cure a problem that is easily curable by changing your style. One is free. The other costs a lot and wears your tires more quickly.

SC~ who can easily double exit ramp posted speed limits.

My car is putting out 310 whp with just the Vishnu Stage 1 setup. That was a $2,400 investment. After I add the cams for the Stage 1+ setup, it should increase by another 20 - 30 whp.

You might be able to get a better price. I know people who have paid a couple hundred over invoice recently.

I think you'll be very happy with the handling. Very few cars can match it. Maybe the tires were cold. I haven't experienced any pushing issues.

I also came from the RWD world after a series of BMWs. It took me 3 AWD cars to finally find one I like. It also took me a while to relearn my habits and learn how to drive AWD....at least better (I'm more in control and can get the car to rotate, etc) than when I started.

AWD will feel like it pushes until you learn. Slow in, Fast out. There's nothing quite like rolling on throttle very hard at apex or a tad after and having the Evo just dig in a pull you through...with NO understeer. The EVO responds beautifully to throttle input....but you gotta be in a better gear. You had no torque to aid cornering at 3k rpm in 5th...or even 4th.

Try just drifting through a corner (sanely) to see how the chassis is set up without throttle at all. Then do something that most cars puke on...apply brakes in mid apex or try and get the car to do something funky with weight transfer via braking....to me it's amazingly stable. Not saying WT wont happen but the car doesnt pull any funny stuff with the tail and steering input while braking. IMO this is the safest car to have fun with on public roads, it's very forgiving.

Overall, you did not get a good impression of the handling while staying below 3k rpm.

The offramp for 85th in Kirkland is rated about 25mph. Ive been to driving schools and know about turn in points and apexs' - remember this was an offramp, with the dealer and a 3k rpm max. At steady state on smooth pavement, the car understeers fairly early and the tires start making noise. I think that a little more front neg. camber should dial most of it out. Is this true or do you need a stiffer rear bar or ???

Fusoguy, you're right. I'm sure I must of downshifted for that speed/RPM.

Any other opinions out there on the differences between the Evo and a RWD car on the track would be appreciated.

BTW, here's a link to my car which is for sale.

Thanks
i'm in the puget sound area. i don't associate with any clubs but i'll autocross soon. maybe in one of the winter events. i have experienced some understeer. i wouldn't say it understeers early, but i am barely hanging on to my license so i'm not driving like a maniac.
